Patented Jan. 13, 1942 UNITED STATES are OFFICE 2,270,095 NONREF'ILLABLE BOTTLE TOP Richard Voltolini, New York, N. Y. Application February 14, 1941, SerialNo. 378,905 6 Claims. (01. 215-2 5 This invention relates to new and useful improvements in a non-refillable bottle top.

The invention has for an object the construction of a bottle top which is characterized by an annular member for engaging into the neck of a bottle and a cup-shaped member mounted on said annular member and extending further into the neck of the bottle, and associated with certain additional mechanism. for preventing the refilling of the bottle.

Still further invention proposed the provision of a valve within the cup-shaped member and cooperative with said valve seat for assisting in preventing the refillingof the bottle.

Another object resides in the provision of a cap for the bottle adapted to be sealed thereon and having an opening, and a hollow tubular shield being mounted on the cap over said opening and associated with a valve head in a particular manner cooperative with the wall of the cap for assisting in preventing the refilling of the bottle.

Still further the invention proposes a novel construction whereby the two valves mentioned previously are connected together so that one assists the operation of the other in a novel manner.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various features of the inventicn are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:

The non-refillable bottle top, according to this invention, includes an annular member It for engagement into the neck ll of a bottle. A cupshaped member I2 is mounted on the member ID and extends furtherinto the neck H and is formed with a rounded bottom end forming a valve seat 12 having a small central opening. A ball valve l3- is'arranged withinthe member [2 and is cooperativewith the valve seat'l2 for closing the small opening. A cap I4 is provided for the bottle and is sealed thereon by sealing material l5. This material may be wax or other sealing material. Ahollow tubular shell 16 is mounted on the cap M. Y The cap 14 is provided with an opening ll arranged coaxially of the hollow tubular shell 16. A valve head 18 is mounted within thev shell 16 and is adapted to rest on the top face of the cap 14 to seal the opening l1.

The annular member is preferably should be of cork material. The. cup-shaped member l2 may be of sheet aluminum or other material. At its top edge it is securedito the annular member l0.-

The cap I4 is'provided with threads M by which it is threadedly engaged on the neck of the bottle. The hollow tubular shell lfi is welded, solderedor any other manner secured to the peripheral vedge of th top- Wall of the .cap M. The valve head 48 consists of a hollow rubber guard member l8 filled and weighted with a glass ball I I8 and having a separate metallic bottom wall 18* adapted to rest on the top wall of the cap I4 over the opening I! for closing the l8 is formed with a plurality. of serrations 18 insuring the passageof liquid through the openings thereof in ,all positions of the valve head la. The upper end of the shell 16 is closed by means of a can W welded in position thereon and'which is formed with a reduced portion 18 through which the liquidmay be poured.

A slotted .top cap Mi is welded over the reduced portion 16 The top cap lt has a plu- I rality of slots [B throughewhich the liquid may pass. A projection I-8 fromthe wall l8 extends through the opening I1 and prevents the valve l3 from closing said. opening I].

- The operation of thedeviceis as follows:

When the bottle is topside upthe parts will assume the positions as shown-in Fig. 2. .In this condition it will be impossible to refill the bottle sinceboththe valves l3 and 18 are enga ed upon their valve seats. The bottle may be emptied by tilting the top end downwards as shown in Fig. 5. In this condition the contents of the bottle may pass through the opening in the cup-shaped member I2, then through the annular member I0, through the opening I'I, around the valve head I8, between the serrations I8, and finally out from the reduced end Iii and the slots I6 of the cap IS". The cap I6 prevents tampering with the valves of the device.

In Figs. 6 to 9 a modification of the invention has been disclosed which distinguishes from the prior form in several respects. According to this form there is a valve head I8 co-operative with the opening II of the shell I4. This valve head I8 includes a hollow rubber member I8 filled and weighted with a glass ball I8 and formed with a plurality of radial serrations I8. These serrations are so arranged that in all positions of the valve head it is possible for fluid to pass through the openings of the serrations and out from the reduced end I6 of the shell IS. A rod 20 is connected coaxially with the separate metallic plate I8 of the valve head I8. This rod 20 engages and supports the valve I3 which is cooperative with the valve seat I2 A feature of this invention resides in the fact that the valve I3 is slidably resiliently mounted upon the lower end of the rod .20. In this construction the weight of the valve head I8 when in position across the opening I! acts to resiliently urge the valve I3 in position upon its valve seat I2 to close the openingformed in the bottom end of the valve seat cage I2. To accomplish this construction the valve I3 is formed with an inwardly extended opening 2| into which the bottom end of the rod 20 is slidably engaged. A means is provided for slidably holding the valve I3 in position upon the end of the rod 20. The rod 20 is formed with a radially extending pin 22 which engages a U-shaped cutout 23 formed in the side wall of the opening 2 I. This U-shaped opening 23 is characterized by a long arm 23 which connects with the exterior of the valve I 3' and which at its bottom continues into a short transverse intermediate arm 23 which in turn connects with a short vertical arm 23. When engaging the valve I3 upon the end of the rod 20 the pin 22 is first passed through the arm 23*- until it reaches a'position adjacent the intermediate transverse arm 23 and then the rod 2|] is twisted to align the pin 22 with the short vertical arm 23. During normal operation this short vertical arm 23 is adapted to house the pin 22 to permit longitudinal movement of the valve I3 with relation to the rod 20.

An expansion spring 24 is mounted within the bottom of the opening 2| and operates between the bottom wall of this opening and the bottom end of the rod 20 for urging the valve I3 into an extended position with relation to the rod 20. In this position the pin 22 will bear against the top end of the short vertical arm 23 of the U-shaped cutout 23 to limit the complete disengagement of thevalve I3 from the end of the rod 20.

The operation of this form of the invention is similar to that described in connection with the previous form of the invention and differs there from by the fact that the weight of the valve head I8 acts to more rigidly ur e the valve I3 in position upon the valve seat I2 to more positively seal the openingin the bottom end of the valve cage I2. When the valves are in their open positions as shown in Fig. 7 the distance between the metallic plate I8 and the valve I3 will be greater than the distance between the opening II and the opening in the bottom end of the valve cage I2 due to the fact that the spring 24 will urge the valve I3 into an extended position with relation to the end of the rod 20. However, when the bottle is again tilted to its normal position as shown in Fig. 6 and the valve head I8 assumes its normal position across the opening I1, the weight thereof will act to compress the spring 24 as shown in Fig. 8 to urge the valve I3 further on to the end of the rod 20 and so seat the valve I3 upon the valve seat I2. The spring 24 is comparatively weak and the weight of the valve head I8 is suflicient to compress the same for the purpose hereinabove outlined. In other respects this form of the invention is similar to that previously described, and like reference numerals are used to identify like parts in each of the several views.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of theinvention as defined in the appended claims.
